Everything your closet needs.

This week, the masterful online men's store Mr Porter celebrates its fifth birthday. And in celebration of the half-decade milestone, the site has partnered with an array of top-notch brands—from Gitman Vintage to Common Projects to A.P.C. to Maison Margiela—on a collection of wardrobe essentials. There's a muted, monochromatic theme throughout the 20-piece capsule, so everything can be easily mixed and matched.

Bonus: Mr Porter is also offering up a chance to win over SGD10,000 credit to spend on the site. All you have to do is browse through the new collection and find the company's signature bowler-hat pin in a photo. Click it, and you can enter to win. So if you're in need of a wardrobe overhaul, you might be able to get it for free. And even if you aren't the lucky prize-winner, you can rest easy in the knowledge that everything from the slim selvage denim to the impeccably made shoes and outerwear is a bonafide investment-worthy option. Shop accordingly.
